Fun facts

Daxiatitan's neck was about 12 metres (39 feet) long, which is longer than a giraffe's neck.1

Only one partial skeleton of Daxiatitan has been found, including neck and back bones, a shoulder blade, and a thigh bone.1

The name Daxiatitan comes from the Daxia River, a river that flows near where the fossils were discovered.1

Daxiatitan lived about 122 million years ago, during the Early Cretaceous period.4

Scientists think Daxiatitan walked with a strong outward swing of its legs, based on the shape of its thigh bone.2

Daxiatitan is part of a group of sauropods called titanosaurs, which were some of the heaviest dinosaurs ever.1
